[Behavioral characteristics of female Wag/Rij rats].

Behavior of male and female WAG/Rij and Wistar rats was compared in the tests assessing the level of anxiety (light-dark choice, open field) and depression-like state (sucrose intake and preference, forced swimming). Females of WAG/Rij rats like males of the same strain exhibited symptoms of depression-like behavior: increased immobility in the forced swimming test and decreased sucrose intake and preference (anhedonia). In contrast to males, females of WAG/Rij rats displayed more distinct signs of increased anxiety as compared to Wistar rats. Both WAG/Rij and Wistar females exhibited increased locomotor and exploratory activity in the open field as compared to males.
